So in the process of doing a very similar project in my car and have found this thread to be of great use. One question I have not been able to answer myself. I want to adapt the USB FM tuner to the cars factory antenna and am having trouble finding a 75 Ohm IEC(Din) Connector

to female motorola standard plug adapter. Does anyone even know if these exist?
[Nexus 7 General] 5c4r7:
Wow! That's pretty slick dude.
[Nexus 7 General] xdaisgreat:
So how do you make phone calls with this setup? I like to keep my phone in my pocket while I drive.
[Nexus 7 General] ImaDouche:
Any progress with the back up cam? Getting a parts list together and it looks like the easy cap is a dead end. Is simple webcam easy to use? I can't seem to find the post where you get the usb cam to turn on when engaging in reverse...
[Nexus 7 General] IIHomieII:
Tablet Talk in the Play Store is a great app for this. You have to install it on both the tablet and phone but when incoming calls come in you can see the caller ID info and picture overlay on the tablet.

Incoming text comes in too so you can see the text message on the tablet in a nice interface and look up previous text messages. Tablet install also has its own dialer so you can call from the tablet.

The call audio is still routed through the phone.

So if the phone is paired up to where you can talk through your car stereo or through a bluetooth headset, this method would work for you.

I have triggers setup with Tasker so that I don't have to actually start the connection. I get in the vehicle and the phone and tablet just find each other automatically and sync-up.

When I walk away from Bluetooth range or turn the car off, they disconnect.

As far as a backup camera..

I have not heard of a better method other than simply using steering wheel controls and the joycon setup to set it up right/easiest.

When you're backing up, you just have one steering wheel button assigned and press it. You can set a 30 second timer with Tasker to return from backup camera to the previous app that was displayed before pressing the button.

This is the easiest way to setup the backup camera, it's just not fully automated but easier..

The only other easy way is for when you have no steering wheel controls and you can tell your tablet to automatically display the camera upon starting the car/charging/phone in range/whatever you prefer..

Then once the car is in motion with your GPS and Tasker you can detect movement and the camera app will restore back to the previous app that was displayed... after say 30 seconds or whatever timeout you prefer..

This way if you want to warm up your car, the camera app will still stay on the screen for 10-15 or however many minutes..

Then once you are in motion it will shut off after about 30 seconds which gives you enough time to back out of your driveway, parking place, etc.

tasker help

So I'm trying to set up taker profiles and I'm failing. I'm just not getting it. I understand setting up variables but I think I'm not understanding the context. I'm just trying to setup my power on= screen, WiFi, GPS, Bluetooth, Mount storage, start music. And power off= opposite.(I think y'all understand what I'm getting at.) Further muddying the situation, the option for screen turn on is red and says not available on my device. Ahhhhhh!!!!! Can someone give me a little help. Maybe even post your profiles that I can download to use/study/modify. Thx for any help.
[Nexus 7 General] timmgrimm:
Sounds like I'm looking to do basically the same setup and tasker profiles as you. I will have a dual outlet wired to the original stereo power wiring with USB running to tablet. It will get power when I turn the key.

I'm hoping to do exactly the same profiles.
[Nexus 7 General] spankiej:
a bumpy and news if you didn't already know

I've been a lurker on this thread, and I just noticed SDR Touch just got presets and is back on the Play Store. To All, what are your impressions?
[Nexus 7 General] Kuchar09:
I like it!!! Wish I could get a better signal but by adding presets to the app makes it actually useful for me. The only thing I think that needs to me added to the app to make it perfect for in my truck is a seek feature, which I believe the developer plans to add in the future.

Now if someone could just find a good solution for an antenna. I currently only get 2 out of my 5 stations I listen to but then again I do live in a small town.
[Nexus 7 General] IIHomieII:
This seems kind of clunky to me compared to using Tunein radio pro, why would we opt for this instead of Tunein radio pro which is also stations in other cities? You can pause a station and record songs/audio from these stations without reception issues.

I just don't see the advantage you have even with good AM FM reception.

I still have my JVC unit installed in my car as well as my tablet so even though I have the ability to grab its remote and utilize it's built in tuner I still prefer Tunein radio pro on the tablet.

Even spending about 2 hours a day commuting in the car between YouTube and Tunein radio pro I never go over my 2.5 gigs of data that I tether from my phone and that is a mere $10 a month.

If there was absolutely no internet around, which just really doesn't happen these days.. why else would you use this instead?

or is the whole point for when there is no Internet?

not trying to sound like an ass..

I just don't get it?
[Nexus 7 General] Kuchar09:
Well there is only 2 reasons I can see. Either you don't have internet or your local channels are not on Tunevin.

Both of these I have issues with, I drive 9 hrs to college and don't have service in multiple spots on my way and it just so happens that I usually get stuck driving when there are blizzards or horrible weather so I try to listen to the radio to see what roads are bad and if I can possibly avoid them.

As far as Tunein I love it!! But it only has 1 or 2 of my local radio stations which is why I usually use MediaU since it has many more stations I listen to and it also has a widget so that you can easily scan through your favorite stations which is kinda nice.
[Nexus 7 General] IIHomieII:
long hours and dead zones..

You definitely go through extreme conditions. I've seen some of those pictures you put up.. snow, blizzards etc.

I got a totally different story going on with only two hours, no dead zones and the Florida Sun..

My Jvc covers this for me but I can see why its a must now either way.

If a truck driver was to have a setup like yours with the DAT and all the other toys I can see where AM/FM would be a must have too.

Your build is definately the best I've seen and it wouldn't be complete without a dedicated tuner.

I haven't been to Disney World in my car since I added all this more than a year ago but I will definately lose internet somwhere when traveling..

so thx for breakin it down ..
[Nexus 7 General] davidadavila:
your thread has helped me with my install greatly thank you, i had one question im looking for a way to be able to change songs with a gesture but i cant seem to find the app that will do this let alone trying to set it up as a gesture, thanks in advance. and also are you achieving ac charge or fast charge with your setup? are you able to maintain everything on navi bluetooth and music streaming without loosing charge? if so how did you accomplish that
[Nexus 7 General] Izzmeister1978:
Hey guys, I have been following for quite some time now and have managed to successfully install the N7 in my car with some issues. I'm currently running Timur's Kernel 3.1.10 FI-2013-03-07@Hexa#1 and his USB Rom as well, last numbers of version are 20130307.022351. My issue is with memory usage. I have practically stripped the N7 of all apps that could be eating too much memory. I'm only running Poweramp, Pandora, etc. I have uninstalled practically everything that could run in the background and take up memory. Even when the tablet is idle memory consumption is upwards of 600mb which from what I gather is just about right. The problem is after I watch a few videos and play music it starts to really lag. I have Task Killer installed so i can see mem consumption and running apps....on it's own after a day or so with no running apps or stuff bogging it down as confirmed by me it starts to get to around 890-894 MB used.....so at that point it's unbearable and barely responds if at all or just shuts down after a while. A reboot is necessary practically every day depending on usage. What am I doing wrong? Is anyone else having this issue? It's not the processor it's actually mem consumption like it handles it so poorly that i have to reboot. Maybe I need a newer version of the rom and Kernel? I don't know.....hopefully Kuchar or one of u guys can help me out....it's really frustrating.....I have a USB hub installed externally with thumb drives connected to it containing movies and music.,.....it all works great until the Mem starts to get used up and then reboot reboot reboot! Thanks guys...
[Nexus 7 General] Happs:
That is fantastic man, great job!
[Nexus 7 General] davidadavila:
i would take out all task killers or any other app that wants to manage you data in such form and reboot
[Nexus 7 General] Izzmeister1978:
The task killer im running is called task killer and doesn't have any services running. I only installed it and run the app to see how much memory im currently using at any given time. It actually works as a manual process killer, u select a service or app and it will kill it for u.....if not it doesn't manage anything. Even before it was installed I had the same issues, I only recently installed it to prove that the N7 is indeed using up all its memory on idle processes. If I reboot the N7, leave it on but with the screen off and don't touch it for a few days like a weekend once I unlock the screen memory consumption is at 870+ mb always......that can't be right.....if anyone can help me please do so.....Thanks

Hi,

very very clean job and tank's for sharing.

i need to know Diod specs used to passing 12v from battery please.
[Nexus 7 General] project_86:
Kuchar09, did you make any progress on a back-up cam? I tried a webcam+cellphone fisheye lens. It worked but the picture was so small it was worthless. Not to mention the webcam lens had a weird issue.
[Nexus 7 General] timmgrimm:
Update: So over the past two days, I've installed my amp and eq, completed all of the wiring, and taken out my oem stereo. I've tested my power and sound with my tablet and everything has gone practically without a hitch. The only thing I've found (and I'm not even sure that it's an issue.) is that when I attempted to use SDR touch I wasn't getting any type of sound. My DVB-T is connected and is getting power but there's no sound/fuzz or anything coming out. I'm using the free version of SDR touch. I'm willing to pay for it, just haven't yet, mainly because I wanted to try it out first. Just curious how it's supposed to work, and/or how to start it working. Thanks for the feedback.

Oh yeah, tomorrow I'm mounting the tablet in the dash. Very excited.
[Nexus 7 General] Kodiack99:
Sounds like maybe a driver issue,what rom are you using?

Timurs usbrom?
[Nexus 7 General] Izzmeister1978:
Any other suggestions? the performance settings are default.....I have to reboot everyday. In the settings tab under running processes it only shows the regular running processes and some cached ones....nowhere near the 860+ mb used after a few hours o fuse....the more apps aI open and close the worse it gets....tehre is plenty of unaccounted RAM being used up and Android won't manage it at all.....if not fot this issue I would be running quite well......Thanks in advance to anyone that can help me....I haven't tried Timur's new ROM....is it any diff or do you guys think it may solve this issue?

Thanks
[Nexus 7 General] IIHomieII:
I want to help but I'm not sure I got all the details..

are you saying when you first got this tablet it ran fine then later when you tried to do the car install/custom kernels is when you started having memory issues

OR

from the first day you got it you have been using it for the car install and you've always been having memory issues?

I am only running stock but I am rooted and using nova launcher and alot of Tasker automation, poweramp, iradar, torque and tablet talk. With all this continually running when I open the browser or angry birds etc. there is zero lag/memory issues.

have you tried running just the tablet for a day with no other hardware devices connected? Flash drives, hard drives, nothing in the aux jack and no bluetooth devices? Wifi would/should not effect it but NOTHING ELSE. If you still have issues just back everything up and try another rom...

these are the tests I would perform in your situation.
[Nexus 7 General] Izzmeister1978:
Thank you for trying to help....when i first got the tablet on the stock rom never an issue. I am now running Timur's Kernel and USB rom.....and I have the RAm issues. Not saying it's the ROM or Kernel, he puts out great stuff but maybe I'm missing something here. I am running poweramp, navigation, Tasker automating 1 job only and tune_in HD radio app....that's it....after a full day of no use the tablet still shows over 860-880+ MB used. If I start using apps and closing them it does the same just much quicker.....I don't get it....Am i the only one with this issue? As for running it without the USB Hub, Flash Drive, DAC, etc....defeats the purpose of the ROM and Kernel combo....I'm about to just wipe it clean and start over with the saem stuff and see if it makes a difference....unles someone else chimes in hopefully Kuchar and suggests something else.....I really don't see where the ram is going. Apps screen under running tab in settings accounts for about 200 MB max plus maybe 100-200 more I would say for system services and that' sit....where is the rest of the RAM going and so quickly? It literally starts to chop the track im playing in poweramp due to RAM consumptions issues......this really is driving me bananas......Thanks.....PLEASE HELP!!!
[Nexus 7 General] timmgrimm:
This question is for anyone whoe;s using a DVB-T. What solution did you come up with for ur antenna? the small one provided with them are very unsightly.
[Nexus 7 General] IIHomieII:
No, it doesn't defeat the purpose of the ram and kernel combo, you're just doing it for a test.

Just like if this was a PC, if there is a problem you would start to break it down one component at a time and then add one component back at a time so in your case you need to disconnect all hardware for a day.

IF there are still issues, try running it in SAFE MODE with no hardware connected.

https://support.google.com/nexus/7/answer/2852139?hl=en

If there are STILL issues, THEN dump the ROM or kernel and start fresh.

If however there are no issues THEN try adding a device. IF there are no problems for a day, do this again untill you find the problem.

Just wiping the ROM could work fine BUT this problem could come creeping back.. better to discover what's causing it now instead of just leaving it as a mystery, only to reoccur all over again..

Determine if its software or hardware by following the steps above and within a few days you'll have the problem licked for good..

dvb-t with SDR touch

I'm working on the build for my N7 in-dash pc and i'm at the FM radio point. I found the DVB-T sticks and the SDR touch app so that I can get FM through that. My question is, has anyone found a good adaptor yet that I can run from my factory antenna plug to the DVB-T plus so that I can keep the stock look but still get the FM signal? I really don't want to run one of the aftermarket antennas if I can avoid it. If I search ebay for "DVB T Antenna Adapter" I get a few options but i'm not really sure if any of these are actually going to work and I dont' want to start throwing money at this if someone has already worked on it and has found something that works. Has anyone done this yet or does anyone have any idea if this will work at all?
[Nexus 7 General] MetalMan2:
A while back I searched for the same solution, but came up empty-handed.

My Audi is a bit of a nuisance in this department, because the factory stereo performs the amplification for the antenna. Therefore, whenever an aftermarket stereo is installed, or in this case a separate FM tuner, a powered antenna adapter is required.

But I digress... my "solution" included buying an adapter from Amazon (which fit the powered adapter I had purchased for an old aftermarket stereo), and I cut the connector off the other end of that adapter and spliced it onto the antenna cable that came with the DVB tuner. Then I attached the antenna amplifier power wire to switched +12V so it would be powered when the ignition is on.

For what it's worth, this "works". I think I need to go back and re-do the connections, but some stations still come out pretty clearly.
[Nexus 7 General] blankdeluxe:
Thanks for the advice. I think I may have found a "fix" for those of us that don't have a power antenna but its really just a work around and I'm not sure if its going to effect the signal at all yet.

Cables needed and what to search on ebay - (copy and paste each into ebay to see the listing)

1. 40-UV41 FEMALE TO FEMALE

2. BNC to standard Motorola male Antenna

3. BNC female jack to IEC PAL DVB-T TV

4. Realtek RTL2832U & Elonics E4000 USB

Like I said. This "should" work but how much loss you end up with after going through all of this is still up in the air. I may end up ordering everything for this just to see how well the signal comes through and to see if it will actually work or not. If anyone else has any input I would love to hear it.
[Nexus 7 General] Acill:
What an amazing project! I had no idea you could do so much with these tablets! I use mine mostly to hack around with stock android, but this thread has me thinking up some cool things I want to be able to try here in the near future!
[Nexus 7 General] pistonrod:
I had the same issues. Tried multiple ROMs/Kernels/betas/stables and could not get that camera to work. If I flashed the ROM after clearing cache/resetting the tablet it would work once and then never again.
[Nexus 7 General] Izzmeister1978:
I would appreciate any help any of you guys can offer me. I'm having RAM usage issues still. I have wiped the N7 clean, internal memory, dalvik cache everything.....clean clean re-install. TWRP then loaded Timur's latest Kernel and USBROM, after having the N7 running the basic apps like Nav and Poweramp maybe youtube a few times RAM consumption goes past 1000mb and then it just wont respond until rebooted. Running apps shows nothing out of the ordinary, I have barely installed any apps. The apps i have installed are trued and true, any ideas? I have tried removing from the car with no connected USB hub or external devices, it just starts slowly climbing in RAM consumption until it's barely responsive or not responsive at all.....anyone else have these issues?

Kuchar if ur still reading this thread please help me out if u can....Thanks guys
[Nexus 7 General] MetalMan2:
Hi, are you installing USB ROM and Timur's kernel?
[Nexus 7 General] MetalMan2:
If you are installing the kernel separately, that could be the problem. Timur's USB ROM includes its own kernel, inside the USB ROM install file (you should not be installing a kernel separately). This included kernel is different than the latest Timur's kernel.
[Nexus 7 General] Izzmeister1978:
I am installing timurs usbrom and kernel. Its the one made for usbrom...
[Nexus 7 General] MetalMan2:
Just to be clear, if you were to install the latest version of USB ROM, you would only install this file:

http://timur.mobi/files/h0fq302/cm-10.1-20130712-USBROM-grouper.zip

And also install GAPPS if you choose. You are not installing any other file, right?
[Nexus 7 General] that_kid:
You should just need to install that file. I just did mine, quick and easy. Do a backup firts just to be safe.
[Nexus 7 General] Izzmeister1978:
Right, that file has the Kernel and USBROM. I install via TWRP the Kernel, then the USBROM followed by GAPPS in that order.
[Nexus 7 General] Kuchar09:
Ok first off sorry I haven't been much help lately everyone!! I've been busy working on my motorcycle and truck for the past few months. Thanks for those who helped with questions while I was away!!! OH and feel free to check out what i've been doing to my bike!!! Plastidip is awesome!!! LINK

I have been playing around with my charger lately. This is the only part I'm not thrilled with but not that big of an issue since I planned ahead and added a charge button when it gets too low. A lot of guys including my self are using one of these. I'm not having as much luck as others since I'm still loosing charge but am going to look into the settings a little more in the near future since some have reported of gaining 15% charge in only an hr. Unfortunately I'm not gaining any charge while using my tablet.

Thanks!!

Man I really not sure what I used and wondering if this might be why im loosing charge even with a DC-DC converter. I would have to say anything 3A and up should be good! I think this would be fine. I'll be sure to check what I'm running next time I take my dash apart!!

I actually have my webcam disabled right now because it wouldn't always close like it should and wasn't thrilled by the picture quality. Keep an eye on this thread tho! Looks like they might have another method similar to the joycon but a little more expensive. http://rootzwiki.com/topic/39717-kernel-module-cm-101-easycap-module/

Nice find!!! might have to give this a shot just for the heck of it and see how it compares to my current setup.

Thanks for the kind words!!

I'm back!! ;) Looks like your getting some help! Can't say I've really ever had this issue but as everyone else said if your installing usbrom you do not need to install the kernal also.... unless things have changed while i was gone lol.
[Nexus 7 General] jeb192004:
I'm planning on trying this. http://febon.blogspot.com/2012/02/1.html?m=1. Gonna order mine next weekend. $77. Then 15 day shipping.
[Nexus 7 General] Kuchar09:
Yupp that seems to be the only solution to be able to use a normal backup cam. I think you still need a joycon to open the app when in reverse until someone is able to get an app to open when the camera turns on from the reverse lights.

Once I figure out my charging issue I plan to order one of these even tho I wish there was a chapter option that worked.

Keep us updated!
[Nexus 7 General] jeb192004:
I already have the joycon for my steering wheel buttons. Traded in my impala for a new truck so I'm working on moving everything over to my truck. Completely redoing how I had it installed. Making it more easily removable.
[Nexus 7 General] Izzmeister1978:
So let me get this straight.....USBROM doesn't need the USBROM kernel installed to work properly? I thought the rom and kernel were a matched set. I know u can install whatever kernel with whatever rom but roms work best with kernels that are optimized for a praticular rom. So do I install a CM10 kernel and just roll usbrom ove rit? Bette ryet, what Kernel and USBROM are u guys running? Let me have the exact Kernel name and version so I can install and run what u guys have. I seem to be the only one with this issue so i must be the only one running something different....makes sense? Thank u all:good:
[Nexus 7 General] Kuchar09:
Do not install any kernel with USBROM! It has everything needed built in. The kernel is if your running CM10 and you can then still have OTG while charging.

Just install USBROM with no added kernel and gapps if you want them.
[Nexus 7 General] Izzmeister1978:
Ok, so what kernel are u guys running with USBROM? Do I just install the factory N7 Kernel that has GAPPS and all that then USBROM or is there a particular kernel I need to run? If I do have to install a factory Kernel then I can do that without wiping the current install of USBROM right? How do i get GAPPS back then if I install factory kernel or a custom kernel and USBROM? A bot confused here.....Thanks for the quick response.
